Screen panel center retainer system

Abstract

A screen panel center retainer system for a vibrating separatory machine utilizes a center retainer that is provided with a retainer base which is adapted to be secured to screen stringer rails of a vibrating separatory machine. A pair of retainer channel legs form an upper portion of the center retainer and have screen panel edge receiving slots. A locking strip, having a wedging tongue, is used in conjunction with the center retainer. The wedging tongue is insertable into the channel on the center retainer which is defined by the two retainer channel legs. Flow control dams and cross dam retainers are used in conjunction with, and in addition to the center retainers and locking strips. The cross dam retainers are provided with locking strip end receiving pockets, to compensate for changes in the length of the locking strips. The screen panel center retainer system is configured to provide a functional, universal installation of screen panels on vibrating separating machines.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of prior application Ser. No. 12 / 216,334, filed Jul. 11,26.08, the disclosures of which are expressly incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention is directed generally to a screen panel center retainer system. More particularly, the present invention is directed to a center retainer system for use in retaining screen panels on a vibrating separatory device. Most specifically, the present invention is directed to a screen panel retainer system that is usable to releasably mount screen panels on screen stringer rails of vibrating separatory machines. A center retainer is secured to each of the screen stringer rails of a generally conventional vibrating separatory machine. The center retainer is attachable to the screen stringer rails using expansion sleeves and expansion pins, or bolts. A lock strip has a wedge tongue that is configured to be receivable in a c...

Problems solved by technology

However, each has its individual limitations which have made each system less than suitable for use in all equipment, regardless of manufacturer and configuration.

U.S. Pat. No. 6,964,341 have been found somewhat difficult to use and have required the provision of screen panel edge strips that have had to be field-installed on the replacement screen panels.

The abutment and alignment of these screen panel edge strips has been somewhat difficult to obtain in the field.

This has increased the time that is required to both initially install the prior systems and to then replace worn screen panels with replacement screen panels.

When a machine, which is operating in an industrial setting, must be taken out of service for repair or replacement of essential elements, that is a loss of that machine's production capac
